Routing game audio between PCs

The trickiest part of a two-PC setup is getting clean audio from the game PC to the streaming PC.

Options

1. Audio interface: send game audio out via line-out to the streaming PC's line-in.
2. Capture card: most cards carry audio with the video signal.
3. Virtual audio cables: route between apps over the network with software like VoiceMeeter (advanced).

Tip: Keep your headset on the gaming PC for the lowest in-game latency. Send a copy to streaming, not the other way around.
